Accurately quantifying total protein concentration is a key to most experiments and is often necessary for isolation, separation, and analysis of proteins by biochemical methods. When it is necessary to determine the total protein concentration in a sample, one of the first factors to consider is the selection of a protein assay method. These choices are typically based upon the compatibility of the method with the samples to be assayed. Each method has its own advantages and disadvantages.

Product Image-1B1301-KIT

VWR® Protein Precipitation Kit

Katalogové číslo: (1B1301-KIT)
Dodavatel: VWR Chemicals
Popis: The Protein Precipitation Kit utilises a simple trichloroacetic acid (TCA) based method to precipitate proteins in complex mixtures. Only protein in the sample is pelleted, while interfering salts and surfactants remain in the supernatant. A gentle acetone wash removes TCA and co-precipitants allowing the end-user to recover the protein in a small volume of buffer.

Protein assay kits, RED 660™

Dodavatel: G-Biosciences
Popis: RED 660™ Protein Assay is a single reagent colorimetric assay that outperforms many commercial colorimetric assays, including Bradford and improved Coomassie/Bradford assays. It offers greater linearity, colour stability, and compatibility with detergents, reducing agents and other interfering agents compared to the Coomassie assays. The single, ready to use reagent allows for rapid analysis of total protein concentration and generates highly reproducible results.
